This is how I achieved this: Mangle Rules: /ip firewall mangle add action=mark-connection chain=prerouting comment=DNS-WAN1 \ connection-state=new new-connection-mark=DNS passthrough=yes port=53 \ protocol=udp add action=mark-connection chain=postrouting connection-state=new \ new-connection-mark=DN...

You must not have two nodes in queue tree with the same packet mark.

say mark "DNS", if QT sees "DNS" mark, how will it decide if it belongs to master UP or Down queue ?

I have changed it to DNS-WAN1-Down and then DNS-WAN1-Up

Thank you

I think I have it sorted.
I set this up on my spare router and the queues seem to be working now based on the Interface.

ether1 is the new WAN interface

I suspect the new flows will only work with Postrouting and input chains?

Like this?

Would I have to jump in the forward chain all the 3rd level children so that the queues will pick it up properly?

Running V6.40.1

Here they are, thank you

@alaskanjackal your scripts are incredible.

How would I implement it with 2 WANs both with different speeds?

Thank you

I have run it yesterday, everything is mapped only to upload on the WAN1 queue

Would this be right? Mangle Rules: 0 chain=forward action=mark-packet new-packet-mark=W1_Upload passthrough=no in-interface=ether1 log=no log-prefix="" 1 chain=forward action=mark-packet new-packet-mark=W1_Download passthrough=no out-interface=ether1 log=no log-prefix="" 2 chain=forward action=mark-...

Thank you so much

What mangle rules do I need to place?

I have prerouting in-interface=wan1 mark-packet=wan1_upload and
Postrouting in-interface=wan1 mark-packet=wan1_download

Would this be correct?

Thank you for the advice. Please can you help me with the following: We have 2 WAN connections load balanced etc. How do I define the different upload and download speeds for each WAN connections using the Queue Trees? - I understand how to get the Upload limit defined by setting the Interface of ea...
